Explanation:
The reaction between benzophenone and phenylmagnesium bromide is a Grignard reaction.
A Grignard reagent is any alkyl magnesium halide compound. In this case, the Grignard reagent is phenylmagnesium bromide.
Reaction of Grignard reagent with a ketone yields all alcohol. Thus, the reaction of benzophenone with phenylmagnesium bromide yields triphenyl methanol.
The mechanism of the reaction and all electron movements are shown in the image attached to this answer.

Answer: 0.3
Explanation:
We know that
Ka = [H+] * [A-] / [HA]
And the acid is 15 % dissociated means that
[A-] / [HA] *100 = 15%
So
[A-] / [HA] = 0.15
Then we know that [H+] = [A-] = 2 molar
Replacing we have
Ka = 2 molar * 0.15 = 0.3
